Abstrakty
Titanium dioxide (TiO2) and Strontium titanate (SrTiO3) are well-known photocatalysts. Today, the photocatalytic activity of dyes on fabrics has attracted much attention. Therefore in this study the photocatalytic activity of nano strontium titanate mixed with nano titania was examined while being coated on cotton fabric under UV irradiation at different nano material concentrations and various pHs. The Central Composite Design (CCD) was used for different variables based on Design Expert software. The crystal size and phase of nano titania and strontium titanate were characterised by XRD. The cotton fabrics stained with two common synthesised dyes were treated under 400 W UV irradiation for 30 hours and their self-cleaning properties were investigated by reflectance spectrophotometer. SEM photos show the pervasion of nano materials. The results show that samples treated with SrTiO3 and TiO2 have higher values of ΔE* as compared with those treated with TiO2 or SrTiO3 alone.
Tytanian strontu SrTiO3 i dwutlenek tytanu TiO2 są dobrze znanymi fotokatalizatorami. Obecnie fotokatalityczna aktywność barwników w materiałach tekstylnych wzbudza ogólne zainteresowanie i dlatego w przedstawionych badaniach fotokatalityczna aktywność nanocząstek SrTiO3 zmieszanych z TiO2 i naniesionych na tkaninę bawełnianą badana była przy napromieniowaniu UV przy różnym stężeniu nanocząstek i różnym pH. W badaniach stosowano program Central Composite Design i Design Expert dla różnych zmiennych. Wielkości krystalitów i faza cząstek TiO2 i SrTiO3 były charakteryzowane za pomocą XRD. Tkaniny bawełniane barwione dwoma powszechnie stosowanymi barwnikami syntetycznymi były naświetlane promieniowaniem UV o mocy 400 W przez 30 godzin a następnie były badane ich właściwości samooczyszczające przy zastosowaniu spektrofotometru refleksyjnego. Zdjęcia SEM pokazują rozłożenie nanocząstek. Wyniki badań wykazały, że próbki zawierające TiO2 i SrTiO3 mają wyższe wartości ΔE* niż próbki zawierające tylko jeden rodzaj nanocząstek.
